Summary
Dome-shaped macula (DSM) was identified in 0.77% of young myopic patients, often not highly myopic. This suggests inherent traits may contribute to DSM development in children and adolescents.
Area of Science:
- Ophthalmology
- Retinal Imaging
- Myopia Research
Background:
- Myopia is a growing global health concern.
- Dome-shaped macula (DSM) is a recognized ocular anomaly.
- Understanding DSM in pediatric populations is crucial for myopia management.
Purpose of the Study:
- To determine the incidence and characteristics of dome-shaped macula (DSM) in children and adolescents with myopia.
- To compare characteristics of myopic patients with and without DSM.
Main Methods:
- Retrospective review of medical records for patients under 19 with myopia (≥ -3.0 D).
- Analysis of optical coherence tomography (OCT) images to identify and measure DSM.
- Comparison of age, best-corrected visual acuity (BCVA), and refractive error between groups.
Main Results:
- DSM was found in 0.77% of eyes (8/1042) from 7 patients.
- Most affected eyes (75%) were not highly myopic (< -6.0 D).
- Patients with DSM were significantly older (15.88 ± 2.36 years) than those without (11.51 ± 4.60 years).
Conclusions:
- DSM can occur in children and adolescents with myopia, even if not highly myopic.
- The low incidence suggests potential underlying genetic or inherent factors in DSM development.
- Further research is needed to elucidate the etiology and implications of DSM in pediatric myopia.

9.3K
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...

01:02The Pineal Gland
4.2K
The pineal gland, a diminutive endocrine structure named for its pinecone-shaped appearance, is situated atop the third ventricle within the diencephalon region of the forebrain. This gland, composed of secretory cells known as pinealocytes arranged in compact cords and clusters around dense particles of calcium salts, plays a pivotal role in hormonal regulation.
The primary secretion of the pineal gland is the hormone melatonin, derived from serotonin. The concentration of melatonin in the...

8.5K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

The retina is a layer of nervous tissue at the back of the eye that transduces light into neural signals. This process, called phototransduction, is carried out by rod and cone photoreceptor cells in the back of the retina.
